Is hashing the same as encryption?

Excuse me, but could you please clarify something for me? I've been hearing the terms 'hashing' and 'encryption' used interchangeably, but I'm not entirely sure if they mean the same thing. Is hashing essentially the same process as encryption, or are there key differences between the two that I should be aware of? I'm particularly interested in how they're used in the context of cryptocurrency and finance, so any insights you can provide would be greatly appreciated.
